LEVI DAVIS, OF WINDSOR, VERMONT.

CHURN.

SPECIFICATION forming part of Letters Patent No, eeaveaaated October 10, 1882,

Application filed June 14, 1882. (No model.)

- improved combinations and arrangements of parts, as more fully hereinafter set forth, and specifically pointed out in the claim.

In the drawings, Figure 1 represents a longitudinal sectional view of the casing or shell of the churn, taken 011 the liney y of Fig. 3, showing the rotary shaft and arms in elevation. Fig. 2 represents a top view of my improved churn, and Fig.8 a transverse sectional view of the same.

The letter A indicates the body or churnvessel, which is approximately semi-cylindrical in cross-section. The said body or vessel, near one end, is provided with a partition, B, preferably of sheet-zinc or other metal, forming a compartment, 0, which may be filled with hot or cold water, according to circumstances, to temper or regulate the temperature of the cream in the churn. The churnbody, near its top, on one or both sides, is pro vided with a series of openings, G, which may be either circular or oblong, as indicated, and

which may be provided with wire-gauze or foraminous covering E, if found convenient.

F indicates the top of the apparatus or churnbody, which sets in a suitable seat at the upper edge of the churn body or vessel, and is provided with apertures D, similar to those in the upper part of the sides of the body of the churn.

The letter H indicates a comlucting-trough, secured to the side of the churn body or vessel opposite the apertures or openings thereof, which serves to conduct the air through the apertures G into the upper part of the churn.

The longitudinal shaft K of the churn is provided with a series of dashers, L, which are radially and spirally arranged, and the casing of the churn with a series of inclined bars, M, so located that the dashers will pass between them as the shaft is rotated. The shaft, at one end, is journaled in a bearing, N, the other journal extending through a box, P, in such manner that it may be titted with a crank, by means of which the said shaft may be rotated.

The operation of myinven tion will be readily understood from the above without further description.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1sm i In combination with the churn-vessel and its rotary shaft, dashers, and inclined rods, the angular chamber communicating with the upper part of the vessel bysnitable apertures,

whereby air may be admitted to the vessel,

the vessel charged with cream, and the discharge of the cream prevented, substantially as set forth. 1

In testimony whereot'I affix my signature, in presence of two witnesses, this 6th day of May,

, LEVI DAVIS. Witnesses:
